SOS Freedom8 Shark Deterrent

Sentinel Ocean Systems Freedom 8 Shark Deterrent

When you're in the water, peace of mind matters just as much as gear performance. The SOS Shark Shield Freedom 8 is a scientifically tested, peer-reviewed personal shark deterrent built for serious ocean users, from freedivers and spearos to surfers, kayak fishers and scuba divers. Using SharkShield's proven electrical field technology, the Freedom 8 creates a three-dimensional protective field around the user that disrupts a shark's Ampullae of Lorenzini, the highly sensitive electroreceptors sharks use to detect prey, causing discomfort and encouraging the shark to keep its distance without causing it any lasting harm. It's versatile enough to attach to virtually any dive setup, surfboard or kayak, and with a maximum operating depth of 50 metres, it covers everything from a dawn surf session to a deep reef dive.

SOS Shark Shield Freedom 8 Key Features

• Electrical Field Technology: Generates a protective field with a strength of greater than 1V/m measured at 1 metre from the centre of the electrodes, creating an effective deterrent zone of approximately 6 metres in diameter around the user.
• Scientifically Tested: SharkShield technology is backed by peer-reviewed research, with demonstrated behavioural influence on white, tiger and bull sharks, including increased approach time and greater stand-off distance.
• Non-Injurious Deterrence: The deterrent effect works purely on shark behaviour, repelling rather than harming the animal, making this a responsible choice for ocean users who care about marine life.
• Operating Depth: Rated to 50 metres (164 feet), covering the full range of recreational freediving, spearfishing and scuba diving applications.
• Battery Life: Delivers 4 to 5 hours of continuous operation per charge (temperature dependent), with a full charge taking approximately 3 to 3.5 hours via the included universal charger, which suits any global voltage or frequency.
• Battery Pack Longevity: The rechargeable battery pack is rated for a nominal 1,000 charge cycles before replacement is expected, giving long service life under regular use.
• LED Battery Indicator: Onboard LED indicator lets you quickly check remaining battery life before entering the water, so you're never caught short.
• Weight: The unit alone weighs just 335 grams (11.8 oz), with the complete setup coming in at 950 grams (2.09 lb) in air and only 69 grams (2.4 oz) in water, making it genuinely unobtrusive during any activity.
• Operating Temperature: Designed to function in water temperatures between 12°C and 40°C (53.6°F to 104°F), covering the full range of Australian coastal conditions.
• Improved Housing and Build Quality: The Freedom 8 features enhanced reliability and durability over previous generations, with a refined housing construction suited to repeated professional use.
• Versatile Mounting: Fits any dive configuration, surfboard leg rope setup or kayak mounting system via a neoprene Velcro pouch, making it genuinely cross-discipline.
• Australian Support: Distributed in Australia with a dedicated Western Australian service and support centre, and backed by a 2-year manufacturer's warranty.

If you spend real time in the ocean, the Freedom 8 is the kind of gear that earns its place in your kit. It won't guarantee anything, but it has the science behind it to meaningfully reduce risk, and that's exactly what you want when you're pushing deeper, staying longer or paddling into sharky water.
